Be it known that I, EMIL Poonnsifir, a citizen of the United States,residing at 'lh'fiin, in the county of Seneca and State of Ohio, haveinvented certain new and useful Improvements in Current-Generators and Iiters for Internal-Combustion Engines,

0 which the following is aspecification.

This invention relates to igniters of the make and break type and inwhich the magneto or current generator is combined therewith as aunitary structure that is fastened to the head or other, suitablepart'of the engine cylinder, the rotor of the generator beingoperatively connected with the inov able electrode of the ign'iter sothat a recip means operatin on the rotor trip finger agalnst the tensionof spring meanscauses the rotor to move to "cocked position while 0 theelectrodes of-- the igni ter are broughttogether, and then released fromsuch cocked "position so that the electro-motive force generated 'by thesudden return movement of the rotor through the magnetic field of thegenerator will produce the igniting current 'Whereby the spark isproduced between the electrodes in, the compimsion chamber of theengine. The. combination of means and instrumentalities above referredto is the subject-matter f my pending ap lication for Letters-Pa ent ofthe Unite States,

.Serial'No. 668,153, filed December 27, 1911,

and the presentinvention relates to improve ments es cially adapted forcombined igniters an generators of the type referred to.

The actuating means. for the rotor and movable electrode is mounted onthe engine cylinder'or other suitable part and is operatively connectedwith some moving mechanism and, has no connection with the magneto origniter, since the actuator, whichmay'be'a push rod, rotating oroscillatory arm or the like, merely contacts'with the trip finger of therotor. generator must be removed from time to time for cleaning theelectrodes and other reasons, it is of great importance tha tltheigniter and generator be replaced in exactly the same position it wasbefore removah otherwise;the push rod will not be disposed in properrelation to the triptinger of the rotor to. accomplish satisfactoryresults in the operation of the engine, generator and igniter. Thereason for this liabilityof the igniter being replaced in a differentposition As theigniter and,

tude between the parts being provided so as to facilitate easy removalof the igniter and to obviate the necessity of careful and receiving thebody of-the igniter, this lstiexpensive machining and fitting of theparts.

-By reason of the liability to error in replacing the igniter, there isprovided an arm or equivalent means onthe igniter body to inter-engagewith a. fixed part on the engine cylinder, so that there can be but oneposition in which the igniter can be attached to the cylinder, and thatposition is the one where the pushrod .or other actuator is in properrelation" to the trip finger of the rotor. As the" result of thisarangement, it is never necessary to adjust the relation of the variousinstrumentalities in replacing the ign'iter when it has been removed forcleani or any other purpose.

In dition to the foregoing objects and advantages, the invention hascertain other minor a vantages which will appear hereinafter as thedescription proccedsgin reference to theiccompa'nying drawings, in.which,

The push rod or actuator has a combinedrccipi'ocatory and rocking movement on a bearing pulley 28 journalcd ona support 29 which is fastened by ll bolt or equivalent means 30 to thearm 10 of the igniter frame, said bolt forming a pivot on which themember 29 can be adjusted to different positions for bringing the freeend of the push rod 25 into proper cooperative rclotion with the tripfinger 25. The trip finger has a tail piece '01. arm 31 which 18 adaptedto be engaged by an arm 32 fastened to the outer end of the movableelectrode ii, the arm 32 being held yieldingly against the arm 31 by ahelical extension spring 33 which has one end connected with the arm 32and the other end anchored at 34 on the ignitcr frame. To obtain theproper set of the sparking points of the electrodes with respect to therotor of the generator, one arm, such as 32, has an adjustable screwwhich engac'es the arm 31. The spring 33 is of less tension thanthe-return springs 23 of the rotor and is sullicicut to maintain thearms 31 and 32 in contact during the firstpart; of the cooking movementof tho armature and to maintain the electrodes in contact during thefinal part of such cool:- ing; movement, it being understood that theelectrodes are normally separated, and that they coinc into contactbefore the rotor or armature finishes iis cocking movement, 1 theposition of the rotor shown by dotted lines in Fig i. it the end of thecocking movement, the push rod "26 sli is off the tip of the tripfinger, and the springs 23, which have been extended or placed undertension during the cocking movement, quickly snap the I'OEOX hack to andbeyond il's normal position, as l]l(ll(21l(2tl by the (lot and dashlines, Fig. 1. This quick movement of the rotor quickly changes thepath'of the magnetic fiux through the pole nieces and rotor,

with the result that a high elect-ro-motive force is induced in thegenerating coils, the maximum electro-moitive force occurring at aboutthe tin'tc the electrodes are separated during the return movement ofthe arm 31 of the trip finger such arm being adapted to strike the arm32 :i hammer blow for effecting a quick separation of electrodes.Byrcferring to Fig, 4, the effect of a defective positioning'of theigniter is clearly depicted. Without the use of the positioningcontrolling psrtsw; 12 and 14, it is possible .for the igniier to besccurealin either the full line posit-ion c or dotted line Sil cylinderwall.

position Z), because of the latitude provided between the igniter bodyand the bolts and in other words, the igniter can be fastened to oneside or the other, of: its true central position to an. extent.correspending; to the gle 0. Thus, the trip arm of the rotor would inthe dotted line position 1: when the igniter is in the dotted raisingthe active end of the trip rod above the tip of the trip finger. Whenthe igniter body is in the full line position athe trip finger isshifted to the right and thdsrmporting roller 28 is lowered so that thepush rod and trip finger will obviously be improperly positioned.' Thesecontingencies can be guarded against by providing the arm 10 on theigniter body and having some means on the fixed part of the engine toengage such arm, such means being the lugs 14-, as in Fig. l, or abolt'or pin 14 engaging in the slot 10 of the arm 10, as in Fig. 9.
